An archaic or regional term, possibly related to bracken (a fern) or to breaking/fragments.
Possibly from Old English or a regional dialect variant. The etymology is uncertain and may relate to either bracken (the fern) or breccia (broken rock).
Brecken appears in historical texts with unclear meaning, which is exactly the kind of word that makes lexicographers excited—obscure words preserve vanished languages and forgotten ways people described their world.
